BIRDSILL HOLLY, OF LOCKPORT, NElV YORK.

PUMP.

Specification of Letters 'Patent No. 29,266, dated July 24, 1860.

To all whom t may concern:

Be it known that I, BIRDsiLL HOLLY, of Lockport, in the count-y ofNiagara and State of New York, have invented certain new and usefulImprovements in `Well Pumps; and I do hereby declare that the followingis a full and exact description thereof, reference being had to theaccom panying drawings, making part of this specification, in which-Figure l, is a vertical section through the center of my pump. Fig. 2,is an elevation of one side of the supporting frame or stock. Fig. 3, isa separate perspective view of the adjusting yoke Gr, and part of thelever H. Fig. 4t, is a plan view of the seat or box of the lower valve.Fig. 5, is a perspective view of the lower valve K, and of the link mconnecting it with the piston. Fig. 6, is a section of the piston andits hollow stem z, in connection with the link m.

Similar letters designate corresponding parts in all of the figures.

The top or stock of my improved pump consists of two cast-iron plates A,formed, as shown in the drawings, with several series of archedopenings, around the edges of which are flanges which give increasedthiclmess, and consequently strength to the metal. The external edges ofthe plates are formed in the same manner. These sideplates are connectedto each other by four cross-bolts, or stretchers, b b, secured by heads,screw-nuts, or other suitable means, upon the outer side thereof, andforming to gether a rectangular frame which rests upon the platform ofthe well, and forms the support of all the operating parts of the pump.Fig. 2, represents the appearance of the front of one of the side platesand Fig. l, being a sectional view of the pump, shows the back or innerside of the other.

The spout-section B, consists of a rectangular flaring basin, with thespout, O, situated upon one side the bottom being provided with anopening of dimensions corresponding with the cylinder or pipe D, withwhich it is connected. This pipe extends downward as far as may berequired to suit the depth of the well, unt-il it connects with thecylinder proper, E, in which the piston,

7', works. Two opposite sides of the spoutsection are curved over in theform of a hook, and rest on the cross-bolts, o, o, as shown in Fig. l;while the spout protrudes through an opening in the side plate providedfor that purpose. The weight of the cylinder and its adjuncts is,therefore, supported wholly by the spout-section resting on the twocross bolts b o; an arrangement at once cheap and effective, as itrequires no fitting of the castings, thereby saving a considerableexpense, while it can be raised or detached readily, and admits ofshifting the spout to either side as convenience may require. By thussuspending the working parts, that rigidity is avoided which isinseparable froin cast iron joints when bolted or secured together, andwhich is often the cause of breakage and damage when the pump issubjected to jarring or vibrations.

The lever H, has its fulcrum in the adjustable yoke G, which isconstructed with an arbor or axis J, directly over the center of thecylinder, or on a vertical line with the piston rod I. The arms, 7c 7c,which form part of the lower section are bolted or otherwise secured toan are L, on each of the side frames. These arcs are provided each withseveral bolt holes, all of which are of the same radial distance fromthe center of the arbor J, so that when the yoke is turned the holes lalc in the lever arms will correspond with either of those in the arc. Byturning the yoke nearer to the center, and placing the piston rod acorresponding distance nearer the fulcrum pin in holes c c provided forthe purpose, the power of the lever is increased to adapt it to wells ofgreater depth, so that no more power is required to work it than forwells of moderate depth. The stroke of the piston is shortened, but thelabor being rendered easy a greater number of strokes may be made in thesame length of time, and

lthe working capacity kept about the same as for shallow wells. Thisbecomes a feature of importance in connection with the constructionwhich enables the cylinder to be placed as low down as is desirable byadding to the pipe D, and piston rod I, and adapts it for use in thedeepest wells. The yoke may be placed at the opposite end of the arc,and the relative position of the handle reversed thereby without turningthe pump should it be desired. The short end of the lever is providedwith a number of holes c c, in either of which the head of the pistonrod may be placed, as before stated, and the lever is so curved as toconstitute an elbowjoint, which gives the greatest power at thebeginning of the stroke, making it start easily.

The piston is provided with a hollow stem L which extends upward for adistance equal to or exceeding the stroke of the iston. It has a nut atthe top into which the piston rod I, is inserted by a screw. The lowervalve K, which is a stem or puppet valve, has a pin i or otherequivalent means of attachment on the top thereof, to which is connectedthe hook of the link m. The upper end of this link passes through thepiston by means of a slot through which the hooked head of the link willpass if in an oblique direction, but when it hangs vertically, as itdoes when left to itself, it cannot be released. lVhen in it playsfreely in the hollow of the stem z, as the piston and valve work inperforming their separate functions, but when it is desired to examineor repair the lower valve this device enables it to be removed withouttaking up the pump, by simply drawing the piston up through the pipe D,which is effected in this manner: The stem of the valve has a stopprojection n on one side, which drops through the notch o Fig. 4, in thevalve seat when it is inserted. This notch occupies such a positionrelative to the pump lever that it has to be turned one quarter of arevolution in order to permit the latter to be connected with the pistonrod. The stop then occupies an annular recess s, in the valve box whichallows it all the vertical movement required by the valve in operating.The link m is flat and inserted in an obl-ong hole or slot in l thepiston which does not allow it to turn; therefore when the piston isturned the valve also turns, and when brought to coincide ure. This is amatter of much importance, inasmuch as the lower valve is liable torequire attention or repairs, as it obviates the removal of the pumentire, which is a work of considerable di 'culty when the well is adeep one.

that I claim as my invention, and desire to secure by Letters Patent,is-

l. The combination of the curve-flanged spout-section B, with theside-plates A, A, and cross-bolts b, Z), so as to furnish a suitable andconvenient support for the pump cylinder and its dependent parts, and aready means of reversing the position of the spout, the wholeconstructed, arranged, and operating substantially as herein specified.

2. The arrangement and combination of the adjustable fulcrum yoke G, andarcs L, L, having adjusting holes therein, with the lever H, having acurved short arm with adjusting holes e, e, therein, all substantiallyas and for the purpose herein speciied.

3. The connecting link m, between the piston and valve K, in combinationwith the notch 0 and stop n, operating substantially as and for thepurposes herein set forth.
